l lll I STOVEPIPE AND FLUE CLEANER.

Specification of Letters Patent.

Patented May 23, 1916.

Application filed June 27, 1914. Serial No. 847,626.

To all whom it may concern:

Be it known that I, EDWIN M. ALBRIGI-rr, a citizen of the United States of America, and resident of Burlington, in the countyof Des Momes, and State of Iowa, have in vented a new and useful Stovepipe and Flue Cleaner, of which the following is a specification.

The object of this invention is to provide improved means for cleaning stovepipes and fines.

My invention consists in the construction, arrangement and combination of elements hereinafter set forth, pointed out in my claims and illustrated by the accompanying drawing, in which Figure 1 is an end elevation of the device in closed or contracted position, the dotted lines indicating the position of the parts when expanded or opened. Fig. 2 is a cross- -section of the device in open or expanded position. Fig. 3 is a side elevation of the device in open or expanded position.

In the construction of the device or tool as shown the numerals 10, 11 designate blades or plates, which combined form a scraping head approximately circular in elevation, each blade or plate being approximately semi-circular in elevation. The blades or plates 10, 11 are mounted on end portions of a spring fork or yoke 12 which forms a handle and operating means therefor. The fork or yoke preferably is formed of round wire or resilient material or substance and has a spring loop or eye 13 at its center. The blade 10 is formed with lips or cars 14, 15 partially cut out of the inner marginal portion of said blade and bent outward and toward each other to form a slide bearing on the forward face of the blade. The blade 10 also is formed with a tongue 16 extending radially from the central portion of the inner margin of the blade and an out-turned flange 17 is formed on the extremity of said tongue. The blade 11 is formed with lips or cars 18, 19 partially cut out of the inner marginal portion of said blade and bent'outward and toward each other to form a slide bearing on the rear face of the blade. The blade 11 also is formed with a tongue 20 extending radially from the central portion of the inner margin of the blade and an outturned flange 21 is formed on the extremity of said tongue. The tongues 16,20 are parallel topics of thin patent may be obtained for and in contact with each other and are confined within the slide bearings formed by the ears 1 t15, 18-19 respectively. It is the function of the out-turned flanges 17, 21 to engage the slide bearings and prevent undue expansion of the blades under tension of the spring fork or yoke 12.

t In practical use of the tool, the spring fork or yoke is grasped manually and compressed so as to bring the blades 10, 11 together as shown by solid lines on Fig. 1. Then the head is introduced into a stovepipe or flue and the tool is rcciprocated manually therein, the device being permitted to expand by relaxing compression of the fork or yoke. Also the tool is rotated within the pipe or flue to bring the convex scraping edges of the blades 10, 11 into contact with all the inner surface of the object being scraped.

Outward pressure of the scraping blades on the surface being scraped is provided by expansive force inherent in the spring fork or yoke.

I claim as my invention- 1. A stove-pipecleaner, comprising a yoke made of spring-wire, flat metal blades mounted rigidly on the ends of said yoke, each blade being formed with central integral tongues adapted to overlie the other blade, each blade being also formed with integral ears at right angles to and overlapping the tongue on the opposite blade, said ears forming slide bearings adapted to embrace the tongue on the opposite blade.

2. A stovepipe cleaner, comprising a yoke made of springwire, flat metal blades mounted rigidly on the ends of said yoke, each blade being formed with integral tongues adapted to overlie the other blade, each blade being also formed with integral cars at right angles to and overlapping the tongue on the opposite blade, said ears forming slide bearings adapted to embrace the tongue on the opposite blade, the extremities of said tongues being turned in opposite directions outwardly and adapted to engage saild bearings and limit expansion of the v0 (e.
